Another application of logistic curve is in medicine, where the logistic differential equation is used to model the growth of tumors. This application can be considered an extension of the above-mentioned use in the framework of ecology (see also the Generalized logistic curve, allowing for more parameters).
Logistic differential equations are useful in various other fields as well, as they often provide significantly more practical models than exponential ones. For instance, they can be used to model innovation: during the early stages of an innovation, little growth is observed as the innovation struggles to gain acceptance.
Logistic Equation. The logistic equation (sometimes called the Verhulst model or logistic growth curve) is a model of population growth first published by Pierre Verhulst (1845, 1847). The model is continuous in time, but a modification of the continuous equation to a discrete quadratic recurrence equation known as the logistic map is also widely used.
This calculus video tutorial explains the concept behind the logistic growth model function which describes the limits of population growth. ... Model Function & Formula, Differential Equations ...
You can tell Malthus was a fairly optimistic guy but let's go through a little bit of the math and a little bit of the differential equations although it's not too, these aren't overly hairy differential equations to think about population. The first way to think about population and I'll express it as a differential equation.
The Logistic Differential Equation ... experiment, or P(t) could be the number of people in a particular country at a time t. A model of population growth tells plausible rules for how such a population changes over time. The simplest model of population growth is the exponential model , which assumes

The Logistic Differential Equation A more realistic model for population growth in most circumstances, than the exponential model, is provided by the Logistic Differential Equation. In this case one’s assumptions about the growth of the population include a maximum size beyond which the population cannot expand.
